Labeler Waste Liner Rewind and Two-Piece Frame Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labelers face inefficiencies due to the accumulation of waste release liner, requiring frequent replacements, and complex maintenance procedures, especially when labeling different products or repairing components, as they are often designed with interfitting parts that make servicing difficult.
Innovation Solution
A labeler with a waste liner rewind mechanism that automatically winds the release liner and a two-piece frame design allowing easy separation for repair or replacement, along with a print mechanism for real-time printing and verification, enhancing maintenance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a traditional labeler design with interfitting components is used, then the labeler can maintain structural integrity, but maintenance and repair become difficult requiring disassembly of multiple components
Solution Approach 1:
The labeler is divided into a head assembly and a cassette assembly that can be easily separated from each other. The cassette assembly contains the label web roll and release liner, while the head assembly contains the application mechanism. This segmentation allows the cassette to be quickly removed and replaced for maintenance or product changes without disassembling the entire labeler.
2Productivity
If label webs are preprinted with specific product information, then product identification is accurate, but replacing label webs for different products becomes time-consuming
Solution Approach 1:
Label webs are preprinted with product information and mounted on rolls in advance. The cassette assembly is pre-loaded with the appropriate label web roll for a specific product before being installed in the labeler. This preliminary preparation eliminates the need to manually handle individual labels during product changes, reducing replacement time.
Solution Approach 2:
The cassette assembly is designed as a universal carrier that can hold different label web rolls for various products. The same cassette structure and mounting mechanism work with any label web roll, allowing quick interchange of different preprinted label rolls without requiring different hardware components.
3Duration of action of stationary object
If the release liner is allowed to accumulate waste, then the labeler can continue operating, but the waste liner tail obstructs the user and labeler functionality
Solution Approach 1:
The release liner is extracted and separated from the label web after labels are applied. The used release liner is wound onto a separate rewind spool that is part of the cassette assembly. This extraction removes the waste liner from the active labeling area, preventing it from obstructing the user or interfering with label application while allowing continuous operation.
4Ease of repair
If the labeler uses a single integrated frame, then structural stability is maintained, but component replacement requires replacement of the entire labeler
Solution Approach 1:
The labeler is segmented into a permanent head assembly and a replaceable cassette assembly. The head assembly contains the motor, control electronics, and application mechanism that remain in the device. The cassette assembly containing the label web roll and rewind spool can be independently removed and replaced. This segmentation enables component-level replacement rather than entire unit replacement while maintaining structural stability through the robust head assembly.

AI summary
A labeler is supported on a frame and includes a waste liner rewind mechanism. The frame may be a two-piece frame, wherein each piece supports a plurality of labeler components. A waste liner rewind wheel is rotatably mounted on one of the frame members, and is capable of supporting the release liner of the label web after the labels have been removed and applied to items. A rewind drive is connected to the waste liner rewind wheel for advancing the waste liner rewind wheel to wind the release liner about the waste liner rewind drive wheel. The rewind mechanism actuates the rewind drive as a function of the amount of tension on the release liner. The labeler may also include a print mechanism positioned along the label web path for printing a desired printed information on the individual labels.
